GAS PUMP AUDITING MACHINE 2 Sheets-Sheet 2 Original Filed March 50, v1954 Inventor W 756323497 life smaai- 4 Home y Patented Sept. 22, 1936 UNITED-STATES PATENT OFFICE r 5 Gas MACHINE I A Application March 30, 1934, Serial No. "718,29 Renewed February 11, 1936 1 Claim. (01. 2814) This invention relates to' an auditing device for gasoline pumps and the like,.the general objest of the invention being to provide a casing having a window therein, hand operated means for feeding a strip past the window so that it panying drawings and specificallypointed out in the. appended claim.

In describing the invention in detail, reference will be had to the "accompanying drawings -wherein like characters denote like or corresponding parts throughout the several views, and in which:- Y

Figure 1 is a front View of a gasoline pump, showing the invention in use thereon.

Figure 2 is a side view, showing the casing in lowered position in full lines and in raised position by dotted lines.

Figure 3 is a top plan view of the device.

Figure 4 is a section on line 44 of Figure 3.

Figure 5 is a section on line 5--5 of Figure 4.

Figure 6 is a section on line 6-6 of Figure 3.

Figure 7 is a diagrammatic View of the circuits.

In these drawings, the numeral l indicates a casing which has the lower rear corner hinged to a backing member 2, as shown at 3, this member 2 being fastened by bolts 4 or the like to the front of the standard of the pump. A cover 6 is hinged to the upper end of themember 2, as shown at 1, this cover closing the casing when the casing is in upright position, and said cover has a window 8 therein, the upper or inner por tion of which is covered by a transparent member 9 and data is placed on the cover, as shown in Figure 3. The cover is formed with a front flange I 0 for engaging the upper part of the front of the casing, when the same is in upright position, and a look I! is provided for locking the cover and casing together. A roll of paper I2 is supported in the lower part ofthe casing and the paper passes upwardly over a guide roll l3 in the upper front corner of the casing and then over a shelf forming member I 4 in the top of the casing, after which the paper passes over a rear guide roll I 5 in the rear corner of the casing, after which the paper passes downwardly and forwardly and around a receiving roll [6, the ends-10f which are supported on the track rails I! connected with the-sides 0f the casing. Spring members [8 tend to hold the roll IS with the paper, thereon against a rubber covered roll I 9 having its ends supported in the casing, with one end projecting therefrom into a small casing 20.- The rubber coating of this roll I9 is preferably corrugated,-as shown. A ratchet wheel 2| is attached to said projecting end of the roll l9 and a handle 22 has one end rotatably connected with a reduced part of said projecting end and carries a spring-pressed dog 23 for engaging the ratchet; in such a manner that as the handle is pulled forwardly through the slot 24 in the casing, the dog will cause the wheel 2! to move and thusimpa'rt movement to the roll l9, which in turn'causes rotary movement of the roll IQandthe paper thereon so-as to feed the paper over the shelf from the main roll I 2. A holding dog 25 is provided for the wheel 2| for preventing retrograde movement of the parts and a spring 26, attached to the handle and a part of the casing 2!], acts to hold the handle in its rearmost position. Thus by manipulating the handle 22, the paper can be fed across the shelf and under the window 8 step by step, and as a part of the paper is exposed through the uncovered part of the window, this part can be Written upon by the attendant so as to record the name of the customer, the name of the attendant, the meter reading, which will indicate the amount of gasoline sold, and also whether the bill is for cash or is to be charged, as clearly shown in Figure 3. On the next movement of the handle to feed another portion of the paper across the shelf, the part last written upon will pass under the glass so that it cannot be changed by the attendant or customer.

A lamp 2! is arranged in a circuit 28 which forms part of a winding for a magnet 29 and this circuit 28 has one terminal connected to a conductor 30 leading from a suitable source of supply and that part of the circuit which forms a portion of the winding of the magnet is connected to a contact 3| for cooperating with a contact 32 on a spring arm 33 which is connected by a conductor 34 to a member 35 forming part of a switch, the other part of which is shown at 36 and is movable toward and away from the part 35 and is connected to the other conductor 30' of the source by the conductor 31. A plunger 38 is arranged in the casing 20 in such a manner that as the handle 22 is moved forwardly, it will strike said plunger and then this plunger 38 will which includes the lamp 21'.

that the magnet will be energized and this'ener gization of the magnet will attract the member, 33 so that the contacts 3| and 32 will engage and thus the lamp circuit will be closed and thiscircuit will remain closed until it is broken by .forward movement of the arm 22 Units feeding acplunger 38 and thus move the member fifiaway from the member 35, which breaks the circuit 7 While Figure 1 shows this lamp attached to a part of a pump,' it can be placed wherever desired and one of the lamps can be attached to-the pump and other lampscan be placed in the office adjacent the pump; Thus the lamp will stay lighted until the arm 22 has been moved forwardly and this lamp or lamps will indicate that the attendant has failed to record the sale.

As will be seen, this invention prevents errors in gasoline sales and protects both the operator and the purchaser and it shows. any omission in the recording of sales and whether or not a charge sale has been overlooked and not written up on a sales pad, as frequently occurs. The invention makes it compulsory that each individual sale be registered or recorded whether it is a charge or cash sale, regardless of who made the sale and givesat an; time the quantity of gas soldand who h I salesman making the sales. tion for the paper and when near the 'end of the forward movement of the arrrnitwill strike the among the staff made the sale. Sales can be checked as to the peak of business and will show the owner when the sales are made and it is practically impossible for a sale not to be recorded as the lamp will continue to burn until the handle has been operated and, of course, before an operator would move the handle he would see whether or not the sale has been recorded. If the machine is re-set and the sale is not recorded, a blank space is shown on the record sheet so that the owner will know that a sale has been made and not recorded. At the end of each days business, the paper taken from the machine will show the number of cash sales, charge sales and the The meter reading on the record sheet will correspond with the meter reading on the pump.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

' It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that suchchanges fall within the scope of the appended claim. 1

- What is claimed is:

In combination, an electric switch for closing the motor circuit of a dispensing pump, means for supporting a movable record receiving sheet in record receiving position, manually operable means for moving the sheet into record receiving'position, an electric signal, means for energizing the same when the switch is closed to operate thepump, and means for deenergizing the electric signal'when said manually operable sheet 7 moving means is actuated.
